Overview
Our main interest in neuroimaging lies in the study of inter-individual differences in neural activation. The understanding of the nature and extent of inter-subjects variation is critical for understanding the neural basis of cognitive processes in normal and abnormal populations.
Part of our research work is dedicated to the study of language processing using neuroimaging techniques (Structural, fMRI and DTI) in healthy controls and patients.
The other part of our research is to provide new tools, mainly using multivariate methods, for a more accurate and comprehensive investigation of neural processes in clinical populations.
From the combinatorics of distributed processing that defines cognitive anatomy, it is important, in neuropsychology and rehabilitation, to know which different combinations of brain areas can support a specific cognitive process.
Research topics
